MCQ

In a transistor the collector current is always less than the emitter current because

A
Collector side is reverse biased and the emitter side is forward biased
✓
A few charge carriers are lost in the base and only remaining ones reach the collector
C
Collector being reverse biased, attracts less electrons
D
Collector side is forward biased and emitter side is reverse biased

✓

Answer

Correct option: B.

A few charge carriers are lost in the base and only remaining ones reach the collector

b
$I_E = I_B + I_C$
